WebNov 17, 2024 · We could use another geometric argument to derive trigonometric relations involving θ − 90 ∘, but it is easier to use a simple trick: since Equations 1.5.1 - 1.5.3 hold for any angle θ, just replace θ by θ − 90 ∘ in each formula. Since (θ − 90 ∘) + 90 ∘ = θ, this gives us: We now consider rotating an angle θ by 180 ∘. WebAdd a comment. 11. The simplest way to find the rotation angle is to take the trace of the matrix, the sum of the diagonal elements. By Cameron Buie's answer this equals 1 + 2 cos ( θ) where θ is the angle of rotation. θ can then be determined up to sign which will depend on the orientation of the axis of rotation chosen.
